    • As assembly of normally open pressure responsive electric switches (10a-10e) is provided using a single lead frame (8) for forming respective discontinuous annuli (12) to serve as contact surfaces for pressure responsive discs (42) and a center contact (14) for each respective discontinuous annulus. The lead frame is overmolded with electrically insulative plastic and the circuit paths are electrically separated from one another by severing selected interconnecting runners (40). Each switching station has a disc (42) sealed by a flexible layer (47) and an O-ring (48). A separate lead (26) can be provided for adding switches of an opposite logic, i.e., normally closed, and a thermistor (38) can be included, if desired. The normally closed switches can be modular or the switches (100, 200) can have contacts formed from the lead frame (89).
    • 由于使用单个引线框架(8)提供常开压力响应电开关(10a-10e)的组装,用于形成各个不连续的环形部分(12),以用作用于压力响应盘(42)和中心触点(14)的接触表面 )。 引线框架用电绝缘塑料包覆成型,并且通过切断所选择的互连流道(40)将电路路径彼此电分离。 每个开关站具有由柔性层(47)和O形环(48)密封的盘(42)。 可以提供单独的引线(26),用于添加相反逻辑(即常闭)的开关,如果需要,可以包括热敏电阻(38)。 常闭开关可以是模块化的,或者开关(100,200)可以具有从引线框架(89)形成的触点。

    • A normally closed pressure responsive switch has upper and lower housings attached to one another with an electrically conductive snap acting disc placed therebetween. The lower housing includes a base having a recessed area in which a stationary electrical contact is mounted. The snap acting disc is placed on top of the base with a side having a convex configuration facing the stationary contact. An electrically conductive member is placed over the disc with a plurality of contact tabs engageable with the outer peripheral portion of the disc. The upper housing includes a retainer having a bore in which a pressure converter slides. Ribs formed on the bottom of the pressure converter are adapted to engage the outer peripheral portions of the disc between the contact tabs and are captured in grooves of the retainer to restrict angular movement of the pressure converter. A flexible membrane is placed on top of the retainer and pressure converter and an O-ring is received on top of the membrane to seal the pressure receiving surface of the flexible membrane to a pressure source when the switch is mounted for use.
